TPMS shows different pressure than pressure gauge

We have the Tireminder TM66 on our Class A. We are finding that many times the sensors have a different reading than the manual tire pressure gauge. not a huge difference but enough to not know whet...

My TPMS (TireMinder A1A) reads higher on all tires than my three gauges (which agree) - 65 on the six tires on the truck and 105 on the four tires on the trailer. I just set the baseline pressure on the TPMS to what the TPMS sensors read when the the tires are inflated properly per the gauges. The alarms will go off at +/- a certain percentage of what is set (and they have - saved us additional damage to the trailer when a tire took a piece of rebar).
